1.   Using n, find the expression for this Think of a Number trick.
Think of a number.
Multiply by 2.
Add 4.
Divide by 2.
Add 6.
Subtract the number you started with.
    A.
    B.
    C.
    D.
    Hint

  2.   Simplify the equation.y = –2(x – 7) – (9 + 5x)
    A. y = –7x + 5 B. y = 7x – 5
    C. y = –16x + 3 D. y = 3x – 16
    Hint

  3.   Find the linear equation.
    A. y = 10(x – 8) + 3x2
    B. y = x + x2 – 7x + 4.9
    C. y = 7x (x– 1) + 4(9.6 –x)
    D. y = 5.2(x – 6) – 2(4 – 3x)
    Hint

  4.   Which equation is not the same as the other three?
    A. y – 3 = 5x B. 5xy + 3 = 0
    C. –5x = –y + 3 D. y + 5x = 3
    Hint

  5.   Which equation is not the same as the other three?
    A. B.
    C. 6 + 2y = x D.
